FIG. 1 , there is illustrated apallet 90 for lifting and transporting, and optionally dumping, alarge container 102, or the like, and acarrier 104 for transporting thepallet 90. In the embodiment ofFIGS. 1-7 , the illustratedcontainer 102 is typically referred to as a tundish, and is typically utilized for transporting molten metal material. It will be appreciated, however, that a transportedcontainer 102 may be an alternative type of container, or be utilized for an alternative purpose. - The
pallet 90 includes abase 92 supported by a plurality ofsupports 94 secured with thebase 92. The plurality ofsupports 94 are spaced from one another and support thebase 92 in spaced relation to a surface 96 (shown in broken lines inFIG. 1 ). In the illustrated embodiment, a pair ofsupports 94 are provided along either side of thebase 92. The illustratedsupports 94 are U-shaped, each of thesupports 94 including a pair of downwardly extendinglegs 98 and one or morehorizontal support elements 100 connecting thelegs 98. Those of skill in the art will appreciate that thesupports 94 may be of an alternative design, however. For example, the three, four, or more downwardly extendinglegs 98 may be provided, with or without ahorizontal support element 100. - The
carrier 104 includes atrailer 106 and atransporter 108 supported on a plurality of ground engaging members 110, 112 configured for propelling thecarrier 104 along a surface. In the illustrated embodiment, for example, the ground engaging members 110, 112 include a plurality of wheels 114, 116 supported on at least onecarrier axle trailer 106 is supported on a first plurality of ground engaging members 110 in the form of trailer wheels 114 supported ontrailer axle 118, while thetransporter 108 is supported on a second plurality of ground engaging members 112 in the form of transporter wheels 116 supported ontransporter axle 120. Those of skill in the art will appreciate, however, that alternate support arrangements are envisioned. For example, thetrailer 106 may be supported on two sets of trailer wheels 114 supported on a pair of trailer axles, respectively, and/or thetransporter 108 may be supported on two sets of transporter wheels 116 supported on a pair of transporter axles, respectively. - The
carrier 104 further includes a prime mover 122, which may be of any appropriate design. For example, the prime mover 122 may be an engine 124 and may be coupled to the ground engaging members 112 by way of adrive train 126. In the illustrated embodiment, the prime mover 122 is disposed with thetransporter 108. It will be appreciated, however, that a portion or the entirety of the prime mover 122 may be alternatively disposed. - The
carrier 104 may further include acab 128 that may be used to carry an operator. In the illustrated embodiment, thecab 128 is disposed with thetransporter 108, although the cab may be disposed with thetrailer 106 in alternative embodiments. In alternative embodiments, however, thecarrier 104 may be remotely operated by one or more controllers (not illustrated) in an autonomous operation. - The
trailer 106 includes a supportingtrailer portion 130 and a forwardly-extendingattachment portion 132 coupled to thetransporter 108 at ahitch 134. Thehitch 134 may be of any appropriate design, preferably allowing thetrailer 106 to pivot relative to thetransporter 108 in order to facilitate thecarrier 104 turning corners. As illustrated inFIG. 3 , for example, thehitch 134 in conjunction with the illustrated ground engaging member 110, 112 including a set of trailer wheels 114 disposed on asingle trailer axle 118, and a set of transporter wheels 116 disposed on asingle transporter axle 120 facilitates thecarrier 104 turning of substantially 90° corners. - The supporting
trailer portion 130 is sized to be received between thesupports 94 of thepallet 90 such that the supportingtrailer portion 130 may be positioned between thesupports 94 to permit transport of thepallet 90 between locations. In order to engage thepallet 90 for transport, at least a portion of the supportingtrailer portion 130 is movable between a lowered position and a raised support position. Referring toFIG. 4 , thecarrier 104 is illustrated with the supportingtrailer portion 130 in a lowered, disengaged position relative to thepallet 90, i.e., as the supportingtrailer portion 130 may be disposed when thetrailer 106 is moving into or out of engagement with thepallet 90. In order to assist in maintaining thebase 92 of thepallet 90 in position relative to the supportingtrailer portion 130, one ormore retainers 136 may be provided. In the illustrated embodiment, thetrailer 106 is provided with a retaining assembly, which includes one ormore retainers 136 disposed to receive aforward end 138 of thebase 92 of thepallet 90. In this way, as the supportingtrailer portion 130 of thetrailer 106 is moved into position below thepallet 90, theforward end 138 of thebase 92 of thepallet 90 may be received in the retainer(s) 136 (seeFIG. 5 ). Those of skill in the art will appreciate that the illustratedretainer 136 may restrain the base 92 not only in a forward direction of thecarrier 104, but also in a vertical direction if a moment is applied to the base in a rearward or sideward direction. - The
trailer 106 andpallet 90 may be provided with additional retaining structures. For example, in the illustrated embodiment, one ormore cradles 135 are provided near the rear of the supportingtrailer portion 130, and one or more cooperatingprotrusions 137 are provided extending from a lower surface of thebase 92 of thepallet 90. In this embodiment a pair ofsuch cradles 135 and cooperatingprotrusions 137 are provided and spaced apart from one another, as may be seen inFIG. 2 . In operation, the supportingtrailer portion 130 is backed into position beneath thebase 92, thetrailer 106 continuing rearward until theretainers 136 engage theforward end 138 of thebase 92 and thecradles 135 engage the cooperatingprotrusions 137. - It will be appreciated that an alternative or additional retainer assembly may be provided, however. By way of example only, the
pallet 90 may be provided with one or more alternative retainers that may be moved into position to engage thetrailer 106. - In order to move the supporting
trailer portion 130 of thetrailer 106 between the lowered position ofFIG. 5 , and the raised support position ofFIG. 1 , at least one carrier actuator 140, 142 is provided. In at least one embodiment, the at least one carrier actuator 140, 142 includes at least onecarrier linkage arrangement hydraulic pressure 151, such as, for example, a hydraulic fluid tank and pump. While the source ofhydraulic pressure 151 is illustrated with thetransporter 108, those of skill in the art will appreciate that the source ofhydraulic pressure 151 may be disposed at any appropriate location, such as, with thetrailer 106. - In the illustrated embodiment, the at least one
carrier linkage arrangement 144 couples the supportingtrailer portion 130 to the first plurality of ground engaging members 110 supporting thetrailer 106, and the at least one carrier hydraulic actuator 148 is disposed between the supportingtrailer portion 130 and the first plurality of ground engaging members 110. In the illustrated embodiment, the at least onecarrier linkage arrangement 146 and carrier hydraulic actuator 150 are provided at thehitch 134 between thetransporter 108 and thetrailer 106, as will be discussed further below. - Any appropriate
carrier linkage arrangement 144 may be provided. Acarrier linkage arrangement 144 may include, for example, afirst trailer link 152 pivotably coupled at thetrailer axle 118 at one end and asecond trailer link 154 at the opposite end of thefirst trailer link 152. The opposite end of thesecond trailer link 154 may be pivotably coupled to the supportingtrailer portion 130. One end of a carrier hydraulic actuator 148 may be coupled either directed or by way of athird trailer link 156 to the trailer axle 118 (seeFIGS. 4 and 5 ), while the other end of the carrier hydraulic actuator 148 is coupled to the supportingtrailer portion 130. In the illustrated embodiment, thethird trailer link 156 is secured with thefirst trailer link 152 such that thethird trailer link 156 pivots with thefirst trailer link 152 relative to thetrailer axle 118. In this way, the first andthird trailer links second trailer link 154, the carrier hydraulic actuator 148, and the supportingtrailer portion 130 itself between the carrier hydraulic actuator 148 and thesecond trailer link 154 form a four-bar linkage. Movement of the carrier hydraulic actuator 148 between retracted and extended positions moves the supportingtrailer portion 130 between lowered position ofFIG. 5 and the raised support position ofFIG. 1 . - While the
hitch 134 may be of any appropriate design, in the illustrated embodiment, thehitch 134 includes the at least onecarrier linkage arrangement 146 in conjunction, which couples thetrailer 106 to thetransporter 108, and the at least one carrier hydraulic actuator 150. While such acarrier linkage arrangement 146 may be of an alternative design, thecarrier linkage arrangement 146 may include, for example, afirst hitch link 158 secured with thetransporter 108 such that thetransporter 108 itself acts as a stationary link. Asecond hitch link 160 may be pivotably coupled to thefirst hitch link 158 and thetrailer 106. Athird hitch link 162 may be pivotably coupled to thetransporter 108 and thetrailer 106. The pivotable coupling of the second andthird hitch links trailer 106 are spaced apart such that thetrailer 106 itself acts as a connecting link in a four-barcarrier linkage arrangement 146 including thetransporter 108 by way of thefirst hitch link 158, thesecond hitch link 160, thetrailer 106 itself between the second andthird hitch links third hitch link 162. The position of thecarrier linkage arrangement 146 may be determined by the position of the carrier hydraulic actuator 150, which may extend to position thecarrier linkage arrangement 146 in the raised support position ofFIG. 1 , and retract to position thecarrier linkage arrangement 146 in the lowered position ofFIG. 5 . - According to a feature of the disclosed
pallet 90, a supportedcontainer 102 may be moved to position to dump the contents of thecontainer 102. In order to facilitate the dumping of a supportedcontainer 102, thepallet 90 further includes afirst platform 170 that is rotatably supported on thebase 92 bycolumn 172. A rotational force may be provided to thefirst platform 170 by any appropriate manual or automatic mechanism, such as, for example, a motor, an engine, or a hydraulic pallet actuator (rotational drive shown generally as 174). By way of further example, thecolumn 172 may include a drive element that extends through the base 92 to be engaged by a drive from thetransporter 108. Thefirst platform 170 may be positioned as illustrated, for example, inFIGS. 1-5 for transport of thepallet 90, or rotated to the position illustrated inFIGS. 6 and 7 for dumping a supportedcontainer 102, as will be explained in further detail below. - The
pallet 90 further includes asecond platform 176 is also adapted to support acontainer 102. Thecontainer 102 may be at least partially received within a recess (see 178) in an upper surface of thesecond platform 176. In order to permit a supportedcontainer 102 to be dumped, thecontainer 102 may be further secured to thesecond platform 176 by any appropriate mechanism. For example, in the illustrated embodiment, theupright structures 180 andsupport brackets 182 extend from thesecond platform 176 along opposite sides of thecontainer 102 to secure thecontainer 102 to thesecond platform 176. - Referring to
FIGS. 2 and 7 , thesecond platform 176 is pivotably coupled to thefirst platform 170 atpivot point 184 for movement between a transport position (seeFIGS. 1-3 ) and a dump position (see position illustrated in phantom inFIG. 7 ). It will be appreciated that theretainer 136 may assist in exerting a retaining force on the base 92 as thesecond platform 176 pivots relative to thefirst platform 170. In this way, thebase 92 andsecond platform 176 are maintained with thecarrier 104 during the dumping process. - In order to provide the pivoting movement of the
second platform 176 relative to thefirst platform 170, thepallet 90 further includes at least onepallet linkage arrangement 186 coupling thesecond platform 176 and thefirst platform 170, and at least onepallet actuator 188 disposed to pivot thesecond platform 176 relative to thefirst platform 170 between the transport position and the dump position. In the illustrated embodiment, the at least onepallet linkage arrangement 186 includes a firstpallet linkage arrangement 186A disposed along a first side of thesecond platform 176 and a secondpallet linkage arrangement 186B disposed along an opposite side of thesecond platform 176. - While the
pallet linkage arrangement 186 may be of any appropriate design, thepallet linkage arrangement 186 of the illustrated embodiment includes a four-bar linkage arrangement. That is, thepallet linkage arrangement 186 includes afirst pallet link 190 that is pivotably coupled to thefirst platform 170 atpivot point 192. Asecond pallet link 194 is coupled to thefirst pallet link 190 atpivot point 196. Thesecond pallet link 194 is further pivotably coupled to thesecond platform 176 atpivot point 198. Accordingly, in this embodiment, the four-bar linkage arrangement includes thefirst platform 170, thesecond platform 176, thefirst pallet link 190, and thesecond pallet link 194, thefirst pallet link 190 being pivotably coupled between thefirst platform 170 and thesecond pallet link 194, thesecond pallet link 194 being pivotably coupled between thefirst pallet link 190 and thesecond platform 176, and the first andsecond platforms - While the at least one
pallet actuator 188 may be of any appropriate design, thepallet actuator 188 of the illustrated embodiment is a hydraulic pallet actuator. Further, while any appropriate number ofpallet actuators 188 may be provided and may be positioned in any appropriate location, in the illustrated embodiment,pallet actuators 188, that is, hydraulic pallet actuators, are provided on opposite sides of thesecond platform 176 and disposed to engage respectivepallet linkage arrangements 186. More specifically, for each of thepallet linkage arrangements 186, thepallet actuator 188 is pivotably coupled to thefirst pallet link 190 and thefirst platform 170. That is, one end of thepallet actuator 188 is pivotably coupled to thefirst platform 170 atpivot point 200, and the opposite end of thepallet actuator 188 is coupled to thefirst pallet link 190 atpivot point 202. Whilepivot point 202 is disposed at a midpoint along thefirst pallet link 190, it will be appreciated that thepivot point 202 could be alternatively disposed, for example, nearer to thepivot point 196. - When
hydraulic pallet actuators 188 are utilized, hydraulic pressure may be provided by any appropriate source ofhydraulic pressure 189, such as, for example, a hydraulic fluid tank and pump. Those of skill in the art will appreciate that the source ofhydraulic pressure 189 may be disposed at any appropriate location, such as, for example, with thetransporter 108, or with thepallet 90. By way of further example, the source ofhydraulic pressure 189 may be coincident with the source ofhydraulic pressure 151 provided for operation of one or more carrier hydraulic actuators 148 and/or carrier hydraulic actuators 150, or may be provided as a separate hydraulic system. - In
FIG. 7 , thesecond platform 176 andpallet linkage arrangement 186 are illustrated in broken lines in progressive positions of dumping thecontainer 102. In the interests of simplicity, thepallet actuator 188 is not illustrated in the progressive positions of dumping. It will be appreciated; however, the distal end of thepallet actuator 188 remains pivotably coupled to thefirst pallet link 190 atpivot point 202. Accordingly, as thepallet actuator 188 extends, thepallet actuator 188 causes thefirst pallet link 190 to pivot relative to thefirst platform 170. Pivoting of thefirst pallet link 190 causes an associated movement of thesecond pallet link 194, and a pivoting of thesecond platform 176 relative to thefirst platform 170. Similarly, as thepallet actuator 188 is retracted, thepallet actuator 188 pivots thefirst pallet link 190, causing the movement of thesecond pallet link 194, and the pivoting of thesecond platform 176 back into position on thefirst platform 170. It will be appreciated by those of skill in the art that the illustratedpallet linkage arrangement 186 andpallet actuator 188 allow thecontainer 102 to be pivoted on the order of at least 180° in at least some embodiments to facilitate dumping of the contents of thecontainer 102. - An alternate embodiment of a
carrier 210 andpallet 212 according to the disclosure is illustrated inFIGS. 8-12 . Structure not specifically described with regard toFIGS. 8-12 is the same as or similar to the corresponding structure inFIGS. 1-7 . As with the embodiment ofFIGS. 1-7 , thecarrier 210 includes atrailer 214 having a forwardly-extendingattachment portion 216 coupled to atransporter 218 by alinkage arrangement 220. In the embodiment ofFIGS. 8-12 ,hydraulic cylinders 222 are provided along either side between thelinkage arrangement 220 and the forwardly-extendingattachment portion 216 of thetrailer 214, only one suchhydraulic cylinder 222 being visible in the figures. Thetrailer 214 further includes a supportingtrailer portion 224 supported by a plurality ofground engaging members 226, here, wheels. - The
pallet 212 includes abase 228 and a plurality ofsupports 230. In the illustrated embodiment, a pair ofsupports 230 are provided along either side of thebase 228. In order to engage thepallet 212 for transport, at least a portion of the supportingtrailer portion 224 is movable between a lowered position and a raised support position relative to asurface 231. Referring toFIG. 8 , thecarrier 210 is illustrated with the supportingtrailer portion 224 in a raised, engaged position. Referring toFIGS. 9-12 , the carrier is illustrated with the supportingtrailer portion 224 in a lowered, engaged position relative to thepallet 212. - In order to assist in maintaining a vertical position of the base 228 relative to the
trailer 214, aretainer assembly 232 is provided between aforward end 234 of thebase 228 andtrailer 214. In this embodiment, theretainer assembly 232 includescarrier ramp pads 236 that extend transversely outward from either side of the forwardly-extendingattachment portion 216 of thetrailer 214, and cooperatingpallet ramp pads 238 at theforward end 234 of thebase 228 of thepallet 212. Thepallet ramp pads 238 are supported by spaced, forwardly-extendingarms 240 that extend from theforward end 234 of thebase 228. - In use, the operator backs the supporting
trailer portion 224 of thetrailer 214 into position beneath thepallet 212 seated on thesurface 231. That is, the supportingtrailer portion 224 is advanced rearward beneath the base 228 between the plurality ofsupports 230 along either side of thebase 228. As thetrailer 214 continues rearward, thecarrier ramp pads 236 engage thepallet ramp pads 238 to dispose thepallet ramp pads 238 substantially subjacent thecarrier ramp pads 236. In order to facilitate engagement between thecarrier ramp pads 236 and thepallet ramp pads 238, theramp pads base 228. In at least one embodiment, thecarrier ramp pads 236 are pivotably coupled to the forwardly-extendingattachment portion 216 such that they may pivot aboutaxis 242. - The
trailer 214 andpallet 212 may be provided with additional retaining structures. For example, in the illustrated embodiment, one ormore cradles 244 are provided near the rear of the supportingtrailer portion 224, and one or more cooperatingprotrusions 246 are provided extending from a lower surface of thebase 228 of thepallet 212. - In order to move the supporting
trailer portion 224 of thetrailer 214 between the raised support position ofFIG. 8 and the lowered position ofFIG. 9-12 , and vice versa, at least onecarrier actuator FIGS. 8-12 is similar to the embodiment ofFIGS. 1-7 , that is at least onecarrier actuator carrier linkage arrangement hydraulic actuator FIGS. 1-7 . Hydraulic pressure may be provided to any carrier hydraulic actuators, includinghydraulic actuators hydraulic pressure 264, such as, for example, a hydraulic fluid tank and pump associated with thetrailer 214. While the source ofhydraulic pressure 264 is illustrated with thetransporter 218, those of skill in the art will appreciate that the source ofhydraulic pressure 264 may be disposed at any appropriate location, such as, with thetrailer 214. - Returning now to the structure of the
pallet 212, thepallet 212 further includes afirst platform 270 that is rotatably supported on thebase 228 bycolumn 272. A rotational force may be provided to thefirst platform 270 by any appropriate manual or automatic mechanism, such as, for example, a motor, an engine, or a hydraulic pallet actuator (rotational drive shown generally as 274). Thefirst platform 270 may be positioned as illustrated, for example, inFIG. 8 for transport of thepallet 212, or rotated to the position illustrated inFIGS. 9-12 for dumping a supportedcontainer 276, as will be explained in further detail below. - The
pallet 212 further includes asecond platform 278 is adapted to support thecontainer 276. Thecontainer 276 may be at least partially received within a cradle (see 280) of thesecond platform 278. In order to permit a supportedcontainer 276 to be dumped, thecontainer 276 may be further secured to thesecond platform 278 by any appropriate mechanism. For example, in the illustrated embodiment, theupright structures 282 andsupport brackets 284 extend from thesecond platform 278 along opposite sides of thecontainer 276 to secure thecontainer 276 to thesecond platform 278. - Referring to
FIGS. 9-12 , thesecond platform 278 is pivotably coupled to thefirst platform 270 at pivot point 286 for movement between the transport position (seeFIG. 8 ) and the dump positions (seeFIGS. 9-12 ). It will be appreciated that theretainer assembly 232 may assist in exerting a retaining force on the base 228 as thesecond platform 278 pivots relative to thefirst platform 270. In this way, thebase 228 andsecond platform 278 are maintained with thecarrier 210 during the dumping process. - In order to provide the pivoting movement of the
second platform 278 relative to thefirst platform 270, thepallet 212 further includes at least onepallet linkage arrangement 288 coupling thesecond platform 278 and thefirst platform 270, and at least onepallet actuator 290 disposed to pivot thesecond platform 278 relative to thefirst platform 270 between the transport position and the dump position. While thepallet linkage arrangement 288 may be of any appropriate design, thepallet linkage arrangement 288 of the embodiment illustrated inFIGS. 8-12 is similar to that ofFIGS. 1-7 in that it includes a four-bar linkage arrangement. That is, thepallet linkage arrangement 288 includes afirst pallet link 292 that is pivotably coupled to thefirst platform 270 atpivot point 294. Asecond pallet link 296 is coupled to thefirst pallet link 292 atpivot point 298. Thesecond pallet link 296 if further pivotably coupled to thesecond platform 278 atpivot point 300. Accordingly, in this embodiment, the four-bar linkage arrangement includes thefirst pallet link 292, which is pivotably coupled to thesecond pallet link 296, which is pivotably coupled to thesecond platform 278, which is pivotably coupled to thefirst platform 270, which is pivotably coupled to thefirst pallet link 292. - While the at least one
pallet actuator 290 may be of any appropriate design, thepallet actuator 290 of the illustrated embodiment is a hydraulic pallet actuator. One end of thepallet actuator 290 is pivotably coupled to thefirst platform 270 atpivot point 302, and the opposite end of thepallet actuator 290 is coupled to thefirst pallet link 292 atpivot point 304. Whilepivot point 304 is disposed at a midpoint along thefirst pallet link 292, it will be appreciated that thepivot point 304 could be alternatively disposed, for example, nearer to thepivot point 298. When one or morehydraulic pallet actuators 290 are utilized, hydraulic pressure may be provided by any appropriate source of hydraulic pressure, such as, for example, a hydraulic fluid tank and pump associated with ahydraulic power module 266 associated with thepallet 212. - In
FIGS. 9-11 , thesecond platform 278,pallet linkage arrangement 288, andpallet actuator 290 are illustrated in progressive positions of dumping thecontainer 276. As thepallet actuator 290 extends, thepallet actuator 290 causes thefirst pallet link 292 to pivot relative to thefirst platform 270. Pivoting of thefirst pallet link 292 causes an associated movement of thesecond pallet link 296, and a pivoting of thesecond platform 278 relative to thefirst platform 270. Similarly, as thepallet actuator 290 is retracted, thepallet actuator 290 pivots thefirst pallet link 292, causing the movement of thesecond pallet link 296, and the pivoting of thesecond platform 278 back into position on thefirst platform 270. - In order to facilitate the full dumping of the contents of the
container 276, thepallet 212 may further be provided with a pushingassembly 306 adapted to provide a concentrated force to a portion of the interior of thecontainer 276. In the illustrated arrangement, thecontainer 276 is provided with a throughhole 308 that may be closed with aplug 310. The pushingassembly 306 may include aprobe 312 adapted for movement by a source ofmechanical movement 314. In the illustrated embodiment, the pushingassembly 306 is associated with thesecond platform 278, theprobe 312 being disposed to advance toward and through the throughhole 308 to apply a force to dislodge residual contents of thecontainer 276, as illustrated, for example, inFIG. 12 . Any appropriate source ofmechanical movement 314 may be provided to advance and retract theprobe 312 from the throughhole 308. By way of example only, theprobe 312 may be advanced by way of ahydraulic actuator 316. In this way, theprobe 312 may be coupled to a rod associated with thehydraulic actuator 316, or theprobe 312 may be the rod itself. It will be appreciated, however, that an alternative arrangement may be provided to provide movement to theprobe 312, such as a mechanical gearing arrangement. Further, while the throughhole 308 is provided in a bottom wall of the illustratedcontainer 276 and theprobe 312 disposed proximally to the bottom wall, it will be appreciated that the probe may be provided at an alternative position relative to the container. For example, the probe may be provided proximal to a side of the container should the through hole extend through a side of the container. It will additionally be appreciated that the pushing arrangement may be mounted for movement into position substantially adjacent the through hole. For example, all or a portion of the pushingassembly 306 may be pivotably mounted or slidably mounted so that theprobe 312 maybe advanced into position relative to the through hole for operation. - It will further be appreciated that the
carrier FIGS. 13 and 14 , for example there is illustrated a fragmentary view of acarrier 320, such as thecarrier 210, utilized in conjunction with ascrap container 322. Those portions of thecarrier 320 not illustrated inFIGS. 13 and 14 may be of any appropriate design, such as, for example, the design illustrated in thecarrier 210 ofFIGS. 8-12 . Thescrap container 322 includes, for example, abox 324 for receiving scrap. It will be appreciated that thebox 324 may be open at its rear portion. Thebox 324 is supported by a plurality ofsupports 326. The plurality ofsupports 326 extend downward from either side of thebox 324, and are spaced apart so that a supportingtrailer portion 328 of thecarrier 320 may be received between thesupports 326. Thesupports 326 may include ramped orarcuate portions 330 toward a rear of thescrap container 322. - As with the embodiment of
FIGS. 8-12 , thecarrier 320 andcontainer 322 may be provided with appropriate retaining structures. For example, in the illustrated embodiment, one ormore cradles 325 are provided near the rear of the supportingtrailer portion 328, and one or more cooperatingprotrusions 327 are provided extending from a lower surface of thebox 324. - It will be appreciated that a
scrap container 322 may not be required to be pivoted a full 180° in order to expel its contents. Aplatform 332 of thecarrier 320 that is pivotably mounted with the supportingtrailer portion 328 atpivot point 336, although alternative or additional pivoting structure may be provided. In order to provide a pivoting force to theplatform 332, aplatform actuator 338 is provided. In the illustrated embodiment, theplatform actuator 338 includes ahydraulic actuator 340 is disposed to engage aportion 342 of theplatform 332 opposite thepivot point 336. Hydraulic pressure may be provided to thehydraulic actuator 340 by any appropriate source of hydraulic pressure, such as, for example, a hydraulic fluid tank and pump associated with the transporter 218 (seeFIGS. 8-13 ). - In the illustrated embodiment, opposed ends 344, 346 of the
hydraulic actuator 340 are pivotably coupled, respectively, to theplatform 332 and to anarm 348 extending downward from the supportingtrailer portion 328. In this way, extension or retraction of thehydraulic actuator 340 results in a pivoting movement of theplatform 332 relative to the supportingtrailer portion 328 and an associated pivoting movement of a supportedscrap container 322. In this way, as illustrated inFIG. 14 ,scrap container 322 seated on asurface 352, thescrap container 322 may be rolled upward on thearcuate portion 330 of thesupports 326 in order to empty the contents of thebox 324. - While the specific embodiment of the
platform actuator 338 described has been ahydraulic actuator 340, those of skill in the art will appreciate that analternative platform actuator 338 may be provided. By way of example only, theplatform actuator 338 may alternatively include a mechanical actuator including a gearing arrangement. Further, while the trailers discussed herein have been described in connection with a tundish and a scrap container, the trailer may be utilized to transport different types of containers as well, such as, for example, a fluid tank. - It will be appreciated that the foregoing description provides examples of the disclosed system and technique.
